Marble Procurement for Large Projects: From Purchase Order to Delivery

Most finishing materials are bought the same way: a specification, three quotations, a purchase order, a delivery note. Marble does not behave like that. It is a natural material bought in batches that cannot be repeated, fabricated to a cutting plan that must be approved before the material physically exists in its final form, and delivered in a sequence to a site that can reject it at the gate if a number on a pallet does not match a number on an approved submittal.

That difference is where marble packages go wrong. Not in the price negotiation, but in the gap between what the purchase order said and what the consultant expected to receive. This guide sets out the procurement path that large projects in the Kingdom actually follow, from the first take-off to the attic stock handed over at completion — and what each document in that chain has to contain to be worth anything in a dispute.

Why marble is not a catalogue purchase

Three structural facts separate stone procurement from almost everything else in the finishing package.

It is batch-bound. Two slabs of the same commercial name, quarried from different blocks, can differ visibly in background tone and vein density. A repeat order six months later is a different material in practice, even when the invoice says the same thing. Quantity has to be committed once, up front, including the wastage allowance and the attic stock.

It is made to order after approval. The slabs exist; the finished pieces do not. Sizes, edge profiles, cut-outs and vein sequencing are produced against a cutting plan, and that plan is a design deliverable, not a fabrication detail. Approving it late compresses the fabrication window, and fabrication is the stage that cannot be accelerated safely.

Acceptance is visual as well as dimensional. A steel section is accepted on a mill certificate. A marble delivery is accepted against an approved physical sample, under project lighting, by a person exercising judgement. If that sample was never formally recorded, “acceptable” becomes an argument rather than a test.

The procurement path, stage by stage

The sequence below is the one that survives audit. Every stage produces a document, and every document is the input to the next stage.

Stage	What it produces	Owner	Cost of skipping it
1. Take-off and area schedule	Quantities split by area, finish and traffic class	Quantity surveyor	Over-ordering, or a shortfall from a closed batch
2. Technical shortlist	Materials filtered by absorption, strength, slab size	Consultant	A beautiful stone that fails in a lobby
3. Supplier prequalification and RFQ	Comparable offers on one scope	Procurement	Quotations that cannot be compared
4. Full-slab viewing and sample approval	Photographed, numbered, signed sample record	Consultant and client	No agreed reference at delivery
5. Block reservation and purchase order	Committed batch, priced and dated	Procurement	Batch sold to another project
6. Cutting plan and shop drawings	Numbered layout, piece list, cut-outs	Supplier, approved by consultant	Waste, mismatched veining, site cutting
7. Pre-shipment inspection	Inspection report against the sample record	Procurement or third party	Rejection discovered at the site gate
8. Phased delivery and acceptance	Delivery log, acceptance note, attic stock	Site team	Storage damage, lost traceability

Stages four and seven are the two most frequently compressed under programme pressure, and they are the two that produce the most expensive failures. Both exist to move the moment of rejection earlier, when rejection still costs a delivery instead of a floor.

What the purchase order must actually say

A marble purchase order that only names the material, the quantity and the price is not a purchase order — it is an expression of interest. At minimum it should carry:

Commercial name of the stone, country and quarry of origin
Block or lot reference for the reserved batch
Finish (polished, honed, brushed, flamed) stated per area
Thickness per application, with the permitted tolerance
Piece sizes or a reference to the approved cutting plan
Edge treatment and cut-out schedule
Net quantity, wastage allowance and attic stock, listed separately
Reference number of the approved sample record
Inspection point: supplier yard, port, or site
Packing specification and pallet marking convention
Delivery programme by phase, with dates and areas
Rejection and replacement terms, including the replacement lead time
Party responsible for the SASO Certificate of Conformity and the SABER shipment certificate
Local content documentation, where the project is government-funded

Items seven and twelve are the ones most often left out and most often needed. Wastage folded silently into a single quantity makes it impossible to prove a shortfall; a replacement clause without a stated lead time is a clause with no teeth.

What the contract adds beyond the purchase order

The purchase order describes the goods. The contract describes what happens when reality diverges from them. For a project-scale stone package, that means:

A batch guarantee. The supplier warrants that the full contracted quantity comes from the reserved lot, and notifies immediately if it cannot.
A defined variation mechanism. Who may approve a change of material, in what form, and what the cost and time consequences are.
Colour variation tolerance. Expressed against the approved sample range, not as “commercially acceptable variation”, which means whatever the losing party says it means.
Replacement and rejection terms. Including who bears freight on rejected material and how long a replacement batch takes.
Attic stock. Quantity, storage location and condition at handover.
Delivery windows. With the consequences of both late delivery and early delivery to a site with nowhere to store it.
Technical support during installation. Scope, response time, and whether it is priced or included.

The inspection gate: what “accepted” means

Inspect where rejection is cheap. That is the supplier’s yard, not the site gate — at the yard, a rejected pallet is a restack; at the gate, it is a truck, a crane and a hole in the programme.

A workable inspection protocol for a project-scale delivery covers four things:

Sampling. Randomly selected pieces from several pallets, not the top of the first pallet. Record which pallets were opened.
Dimensions. Thickness measured with a caliper at several points per piece, plus length, width and squareness against the stated tolerance.
Appearance. Compared against the approved sample range in daylight, with the extremes of the accepted range physically present for reference.
Documentation. Batch reference on the packing list matched to the reserved lot, and the inspection signed and dated by a named person.

Everything found at this gate is a negotiation. Everything found after installation is a claim.

Saudi compliance: the two certificates that gate customs

Dimension stone is a regulated product in the Kingdom. The SASO Technical Regulation for Building Materials, Part 4 covers granite, marble, limestone, slate and travertine dimension stone under HS headings 6801, 6802 and 6803, and requires a Certificate of Conformity issued by a notified body approved by SASO. The obligation sits with whoever places the product on the Saudi market — the manufacturer, the importer, or the agent of a foreign manufacturer.

In practice that runs through the SABER platform in two steps: a Product Certificate of Conformity for the product itself, then a Shipment Certificate of Conformity for each consignment. Since SABER was integrated with the FASAH clearance platform, a shipment without a valid shipment certificate is not granted access to the market. A container of approved, inspected, perfectly matched marble sitting at a port because nobody was named as responsible for the certificate is a procurement failure, not a logistics one.

Two consequences for the purchase order. First, name the party responsible for obtaining and maintaining both certificates. Second, require the certificate references to appear on the shipping documents, so the clearance agent is not chasing them after the vessel has arrived.

Government-funded projects: the local content layer

On public sector work there is a second requirement. The Local Content and Government Procurement Authority operates a Mandatory List of national products, and has introduced minimum local content percentages as a condition of access to that list. According to the Saudi Press Agency, 233 products come under the minimum local content requirement from 1 August 2026 — a phase that explicitly includes ceramic and porcelain tiles — with a further group following in 2027, and the targeted ratios reviewed periodically.

Stone is not named in that first phase, but the direction of travel is clear and the list is live. On any government-funded project, check the current Mandatory List and the applicable percentages before assuming an imported finish is compliant — and build the answer into the tender response rather than discovering it at evaluation.

Payment milestones that match delivery reality

Stone suppliers carry real cost before anything ships: the block is reserved, then cut, then finished. Payment terms that ignore that get either a reluctant supplier or an unsecured buyer. The structure below reflects what is typical on project-scale orders in the region; the split is indicative and should be set against the specific lead time and supplier relationship.

Milestone	Typical share	What it should be tied to
On order and block reservation	around 25–30%	Written confirmation of the reserved lot reference
On approval of the cutting plan	around 20%	Consultant-approved shop drawings, not the supplier’s submission
On successful pre-shipment inspection	around 30–40%	Signed inspection report, not the packing list
On site acceptance of the final phase	around 10%	Delivery complete, including attic stock
Retention	around 5%	Released after the defects liability period

The principle matters more than the percentages: every payment should be released against a document that someone on the project side signed, never against a document the supplier issued alone.

A procurement timeline you can lift into your programme

Work backwards from the date installation starts. The durations below are indicative averages for an imported project quantity; local material shortens the supply leg considerably, and a bookmatched feature wall lengthens the fabrication leg.

Stage	Indicative duration	Runs before installation by
Take-off, shortlist, RFQ	3–4 weeks	Longest lead
Slab viewing and sample approval	2–3 weeks	—
Block reservation and PO	1 week	—
Cutting plan approval	1–2 weeks	—
Fabrication	3–6 weeks	—
Inspection and shipping	2–6 weeks	—
Site mock-up and sign-off	1 week	Immediately before bulk installation

Add float to the two legs you do not control: quarry availability and shipping. The rest of the chain is inside the project’s own gift.

The three documents that end most disputes

When a stone package goes to a claim, the file is usually thin. Three documents, kept properly, resolve the majority of arguments before they escalate:

The approved sample record — photographs of the approved slabs, the batch reference, the date, and the signatures of the parties who approved them.
The approved cutting plan — the numbered layout the installation was supposed to follow, which also proves what the wastage allowance was calculated against.
The delivery and inspection log — what arrived, when, which pallets were opened, what was measured, and who signed.

Frequently Asked Questions

Can a marble package be bought on a framework agreement across several project phases?

It can, but the batch problem does not go away. A framework fixes commercial terms; it does not reserve material. If phases two and three must match phase one visually, the full quantity has to be reserved at the start and stored, either at the supplier’s yard or on site. Otherwise the framework buys you price certainty and a visible colour break.

Who should hold the attic stock, the contractor or the client?

The client, in a location the facilities team controls, because the repair it exists for will happen years after the contractor has demobilised. Hand it over formally, with the batch reference recorded, and store it flat and covered — attic stock that has been stacked against a wall in a plant room for three years is rarely usable.

Is a third-party inspection worth its cost on a stone package?

On an imported project quantity, usually yes. The cost of an independent pre-shipment inspection is small against the cost of rejecting material after it has been shipped, cleared and delivered. On a local supply where the project team can visit the yard themselves, the value is lower — the inspection still has to happen, just not necessarily by a third party.

What happens if the quarry cannot supply the full reserved quantity?

This is why the contract needs a notification obligation with a deadline attached. Discovered early, the options are a revised layout that confines the original material to defined zones, or a full re-selection before fabrication starts. Discovered after installation has begun, the options narrow to a visible mismatch or demolition — which is precisely the situation described in when changing the marble type becomes a risky decision.
